[Solved]Getting text over players head

Is it possible to get text to hover over a 2d characters head in game? If so, how could i get the text to follow the character? Do I use the canvas just the same?

 

If you need the text to be 3D (if you zoom in, the text maintains its relative size), you could make a World Space mode Canvas as a child of your character.

If the text should always stay the same size on-screen, you can use Camera or Overlay mode Canvas, and write a script to convert the character position to screen space and update the text position on screen.

 

and this is viable for a 2D game? the text I want to be over the NPC heads and the NPCs will be moving.

 

Yep, both would work for your 2d game.

 

Ok I gave it a try but no luck yet. Any example of implementing this so i can work from it?

 

Something like this:

Code (CSharp):

1. // on the character
2. [SerializedField]
3. Text mTextOverHead;
4. Transform mTransform;
5. Transform mTextOverTransform;
6. void Awake() {
7.    mTransform = transform;
8.    mTextOverTransform =  mTextOverHead.transform;
9. }
10. void LateUpdate() {
11.    Vector3 screenPos = Camera.main.WorldToScreenPoint(mTransform.position);
12. // add a tiny bit of height?
13. screenPos.y += 2; // adjust as you see fit.
14. mTextOverTransform.position = screenPos;
15. }

 

I will go take a look, thanks for the tips. I will try to build off this

 

If you use a world space canvas as a child of your character, then it will automatically follow the character around as a child object. You just have to size and position the canvas and child UI elements above the character.

 

Yep, world canvas is cool, too. And in 2d (or 3d if you don't care about the size changing) they are probably pretty easy.
Doesn't hurt to know a few options, though.

 

What should the event camera be? a new camera instance?

 

I don't know for sure, but if you aren't taking events on text over their heads, it can just be empty. If it does take events, try just the normal camera?

 

Gotcha, it works. I was expecting some issues since it was 2D but once I set it up properly just needed to set the world mode and position as needed.
